The advent of the nanotechnology era offers a unique opportunity for sustainable agriculture provided that the exposure and toxicity are adequately assessed and properly controlled. The global production and application of cerium oxide nanoparticles (CeO-NPs) in various industrial sectors have tremendously increased. Most of the nanoparticles end up in water and soil where they interact with soil microorganisms and plants. Investigating the uptake, translocation and accumulation of CeO-NPs is critical for its safe application in agriculture. Plant uptake of CeO-NPs may lead to their accumulation in different plant tissues and interference with key metabolic processes of plants. Soil microbes can also be affected by increasing CeO-NPs in soil, leading to changes in the physiology and enzymatic activity of soil microorganisms. The interactions between CeO-NPs, microbes and plants in the agricultural system need systemic research in ecologically relevant conditions. In the present review, The uptake pathways and in-planta translocation of CeO-NPs,and their impact on plant morphology, nutritional values, antioxidant enzymes and molecular determinants are presented. The role of CeO-NPs in modifying soil microbial community in plant rhizosphere is also discussed. Overall, the review aims to provide a comprehensive account on the behaviour of CeO-NPs in soil-plant systems and their potential impacts on the soil microbial community and plant health.
纳米技术时代的到来为可持续农业提供了独特的机会,前提是充分评估和适当控制其暴露和毒性。全球生产和应用氧化铈纳米颗粒(CeO-NPs)在各个工业部门急剧增加。大多数纳米颗粒最终进入水和土壤中,在那里它们与土壤微生物和植物相互作用。研究 CeO-NPs 的吸收、转运和积累对于其在农业中的安全应用至关重要。CeO-NPs 的植物吸收可能导致其在不同植物组织中的积累,并干扰植物的关键代谢过程。土壤微生物也可能受到土壤中 CeO-NPs 增加的影响,导致土壤微生物的生理和酶活性发生变化。在农业系统中,CeO-NPs、微生物和植物之间的相互作用需要在生态相关条件下进行系统研究。在本综述中,介绍了 CeO-NPs 的吸收途径和在植物体内的转运,以及它们对植物形态、营养价值、抗氧化酶和分子决定因素的影响。还讨论了 CeO-NPs 在改变植物根际土壤微生物群落中的作用。总的来说,该综述旨在全面描述 CeO-NPs 在土壤-植物系统中的行为及其对土壤微生物群落和植物健康的潜在影响。
